I believe I have to go with the "dressing appropriately" theory. When you come from colder climes and you get a 60 or 70 degree day it's almost shorts and t shirts. Yesterday we played golf at 2:30 in shorts, but by the end of 9 holes things were cooling down. The drive home after dinner we about froze to death. Would have never made that mistake up North. And I'm talking North Carolina as our last stop before TV.
